For some reason, people love to assume that I have at least one kid. Honestly, I cannot figure out why. Do fat ladies just seem motherly? Is it because I'm always in good spirits, and people assume that equals some kind of affinity for motherhood?
I've never really been comfortable around kids, and I find that the older I get, the more true that is. I couldn't relate to them when I was one, and I haven't gotten any better at it.
I think far too many people have kids because they're "supposed to" or it's the "natural order of things" or whatever. I didn't get married to have kids, I got married to have a husband. I'm not less of a woman for not being a mom, even though people definitely seem to look at it that way.
Parenthood is NOT for everyone, and I think that people should consider it carefully before making a decision either way. For me - I don't have the patience, energy, altruism, or deep love of children to make a good mother. I'd be worried ALL the time for one reason or another. Not for me.
More power to you if you can devote your life to having kids, though. Somebody needs to do it!

Truly great parents really make me happy, which is one of many reasons I don't have kids - because I don't believe I'd be one.
